The study suggests that closing the life cycle of PET through construction materials could help address both plastic pollution and the environmental footprint of the building industry.
Integrating Plastic Waste into Concrete: Sustainable Solutions for the Environment
This review examines research on incorporating plastic waste into concrete as a partial replacement for conventional aggregates and cement. Researchers found that adding recycled plastic can reduce concrete density and improve thermal insulation properties, though it generally decreases compressive strength at higher replacement ratios. The study suggests that optimizing plastic content and treatment methods could make this approach a viable strategy for diverting plastic waste from landfills.
